Few months back i have the same requirement. I created function
getUniqueElements(workListErrorFlag,"flag").
This function takes the XMLList and the xml node name for which you
want the unique elements.In your case it should be "filter" .It may
be possible that you have to make some small chnages.
private function getUniqueElements
(list:XMLList,xmlTag:String):XMLListCollection
{
var xmlCollection:XMLListCollection = new
XMLListCollection();
var uniqueEvents:ArrayCollection = new
ArrayCollection();
for each( var systemxml:XML in list)
{
var system:String = systemxml.children
().length() > 1 ? systemxml[xmlTag].toString():String
(systemxml.toString());
if ( !uniqueEvents.contains(system) )
{
uniqueEvents.addItem(system);
xmlCollection.addItem(new XML
(<{xmlTag}>{system}</{xmlTag}>));
}
}
return xmlCollection;
}
